Definitions

• the invention relates to an umbrella, in particular a large umbrella, garden umbrella, parasol and the like.
• an umbrella stick with an umbrella stick, a telescopically displaceable stick part in the umbrella stick, to which the roof poles are articulated by means of a crown, and with support struts between a runner which can be displaced along the umbrella pole and the roof poles, and with a roof covering.
• the displaceable stick part is connected to a threaded spindle mounted in the umbrella stick and the rotor is connected to the stick part by means of a flexible tension member guided over a deflection roller.
• Such a screen is described for example in US Pat. No. 4,424,824.
• the stick part which is slidably mounted in the umbrella stick and which carries the roof poles, with the application of a small force, and thereby to raise the runner and bring the roof poles into the open position by means of the support struts and support in this.
• the movements of the stick part and the rotor are opposite.
• the pole section is lowered by means of a threaded spindle, while the runner is raised by the flexible tension member.
• the telescopic pole section is raised while the runner slides down on the umbrella pole.
• the runner is moved downwards by its own weight and by the proportionate weight of the support struts and roof bars.
• the manual control The supply mechanism is preferably used for umbrellas with a span of 4 to 8 m in diameter. It is essential here that an umbrella is obtained, the umbrella roof of which can be stretched extremely tight when the umbrella is open.
• the object of the invention is to further develop an umbrella of the type mentioned in such a way that an umbrella is obtained whose umbrella roof runs more or less concave from the umbrella tip to the roof rod ends, so that a kind of pagoda shape results. It is important that the canopy is under tension from the tip of the canopy to the ends of the canopy.
• the invention is characterized in that a further movable along the pole part crown is provided as a crown on which the roof covering attached to the roof pole ends is attached, that the crown has pressure bars, the lower ends of which are guided by a common guide part along the pole part and that an annular support is provided on the umbrella stick as a support for the guide part.
• crowns, pressure rods and guide part form a rigid, stable composite part.
• the pressure rods can be drilled through the like. be passed through the roof pole crown so that physical disability cannot occur when opening and closing the screen.
• the ring-shaped support is expediently arranged at the upper end of the umbrella pole. This can receive receiving elements for the pressure rod ends, the receiving elements being adjustable in height.
• the pressure rods expediently have stops for limiting the displacement of the crown. Such stops preferably consist of thickening of the bars.
• the radial segments of the textile roof covering are cut more or less concavely on the long sides of the triangular structure.
• Fig. 2 shows the screen of Fig. 1 in the open
• FIG. 5 + 6 illustrate the drive device for the
• Fig. 8 gives a phase overview of the movement of the crown over the closed to the open screen in view and in the diagram.
• Umbrella stick 2 is provided, in which a stick part 3 telescopically displaceable in the umbrella stick 1 is provided, at the upper end of which a crown 4 is attached, to which the roof rods 5 are articulated.
• a runner 6 is slidably arranged along the umbrella pole 2, on which support struts 7 are articulated, which with their other end 8 engage the roof rods 5 in an articulated manner.
• a threaded spindle 10 which is immovably mounted on an angular gear 11 at the lower end.
• the threaded spindle 10 is advantageously designed as a trapezoidal threaded rod.
• the angular gear 11 is fixedly mounted in the umbrella stick 1 on a holder 12 which is attached to the umbrella stick.
• the angular gear can consist, for example, of a worm and a worm wheel, which is connected to the threaded spindle 10 in a rotationally fixed manner.
• a threaded nut 13 is arranged on the threaded spindle 10 and is fastened to the stick part 3.
• the threaded spindle can be rotated by means of a hand crank 14.
• the stick part 3 and the runner 6 protrude a flexible tension member 15 in connection with each other, which runs over a deflection roller 16.
• the flexible tension member advantageously contains a wire rope; a chain or the like can also be used.
• One end of the tension member 15 is fixedly attached to the stick part 3 by means of a fastening member 17, for example a screw or the like, while the other end of the tension member 15 is firmly connected to the rotor 6 at 18.
• the spindle 10 is by means of
• Roof poles 5 is supported by means of the support struts 7.
• the roof pole crown 4 is lowered.
• a further crown ie an upper crown 20, is provided, to which only the roof covering 21 is attached or suspended, while the lower edge of the roof covering 21 is connected to the ends of the roof rods 5.
• the lower ends of the pressure bars 22 lead to a plate piece 23 firmly connected to them.
• the top crown 20, pressure bars 22 and the plate piece 23 as a stabilizing plate form an inherently stable composite part which as a whole can be displaced vertically.
• the plate piece 23 is equipped with a kind of feet 24.
• an annular support 25 is arranged at the upper end of the umbrella pole 2.
• the support 25 has receiving elements 26 for the pressure rod ends, the receiving elements 26 being adjustable in height.
• the receiving element elements 26 are advantageous infeed centering, elastically damping, upward open receptacles! ager.
• the lower ends of the pressure rods move into these and sit softly when the screen is opened.
• the lower ends of the pressure rods are designed on the one hand so that they can be unlocked and positively guided when entering and putting on the bearings 26 z, on the other hand the height can be adjusted in a fine adjustment range.
• the height adjustment of the ends is used to optimize the body shape of the open umbrella.
• the compression rods 22 pass through bores 27 of the roof rod crown 4.
• the pressure rods 22 are provided at an appropriate height with stop elements 28 which limit the displaceability of the roof rod crown 4.
• the stops 28 advantageously consist of thickening of the rods themselves at the point in question.
• the runner 6 Since the runner 6 is connected to the lower end of the inner movable stick part 3 by a rope 15, which is guided and guided via the rope pulley 16 which is fixedly attached to the upper end of the outer, non-movable umbrella stick 2, the lowering of the inner stick part together with crowns is effected at the same time the runner 6 starts up. The crown and the runner move in opposite directions.
• the still changing geometry of the roof construction against the stationary cone 20 which remains stationary in the room causes a complete, wrinkle-free stretching of the roof covering, the complete stretching of the roof edge arches and, for example, attached textile side panels under recognizable high mechanical material tension (peripheral prestressing), a clearly visible (by the way also audible: clear reverb effect when speaking under the umbrella) high material tension along the radial line of curvature to the crown (radial preload) and a clearly visible, idealized or optimized shape of the entire roof or umbrella body (pagoda).
• the umbrella When the umbrella is closed, the roof body relaxes with every turn of the hand crank. There is an excess length in the fabric reference lines or lines between the roof rod ends and their opposite fastening points on the top crown.
• Crown 20 together with pressure rods 22 and stabilizing plate 23 initially do not move upwards; Only when the roof rod crown with the passage bores in it abuts the lower edge of the upper thickenings 28 of the pressure bars 22 does the top crown also rise. This means that the roof rod crown 4 takes the top crown 2 upwards. Both parts move upwards together at a constant height distance. At the driver point concerned, the above-mentioned excess length in the fabric of the roof covering systematically eats up again. It disappears as soon as the umbrella is closed. The relevant excess lengths only occur temporarily during the opening and closing process.
• the radial textile segments of the open pagoda-shaped screen or the roof covering of the Umbrellas are not triangular in their plan execution and put together; rather, all three sides of an imaginary isosceles triangle are concave in relation to the area of the triangle.
• Leg side of a roughly triangular radial segment is therefore opposite the mirror-image concave leg side of the next adjacent, also roughly triangular radial roof segment.
